Abstract
Combustible gases from a solid fuel are produced by pyrolyzing the fuel in a pyrolyzer which also produces carbonaceous material. The carbonaceous material from the pyrolyzer is combusted in a furnace to produce combustion products that include hot flue gases and ash particulate. The combustion products are separated into a plurality of streams, one of which contains flue gases, and another of which contains hot ash which is directed into the pyrolyzer. Finally, the stream of flue gases from the furnace is used to dry the fuel that is supplied to said pyrolyzer.
